for mail id validation it not working. for eg. if user even enter mailID: "@", it accepts that as well. So, acc to me for mailID code should be : public string EmailID { get {return _emailID;} set { System.Text.RegularExpressions.Regex r = new System.Text.RegularExpressions.Regex(@"[a-z0-9!#$%&'*+/=?^_`{|}~-]+(?:\.[a-z0-9!#$%&'*+/=?^_`{|}~-]+)*@(?:[a-z0-9](?:[a-z0-9-]*[a-z0-9])?\.)+[a-z0-9](?:[a-z0-9-]*[a-z0-9])?"); if (!r.IsMatch(value)) { throw new ArgumentException("A valid EmailID is required"); } _emailID = value; } }
